3 Description
The TPS543B25T is a high-efficiency, 18V, 25A,
synchronous buck converter employing an internally
compensated, fixed-frequency advanced current
mode (ACM) control architecture, which while always
operating under FCCM, generates output voltages
from 0.5V to 7V. The device is capable of providing
high efficiency while operating at a switching
frequency up to 2.2MHz, making the device an
excellent choice for designs requiring a small design
size. The fixed frequency controller can operate from
500kHz to 2.2MHz and can be synchronized to an
external clock using the SYNC pin. Additional features
include a high accuracy voltage reference, two-wire
remote sense, selectable soft-start times, monotonic
start-up into prebiased outputs, selectable current
limits, adjustable UVLO through the EN pin, and a full
suite of fault protections.
The TPS543B25T is available in a small 2.5mm ×
4.5mm HotRod? WQFN-FCRLF package.
